We had the same problem while playing with the free Windoze KCam (http://www.kellyware.com )
but it turned out to be: we had just connected the S&D parallel port pins to the
driver, BUT NOT A GROUND (ie a logical ground from the driver to one of the
ground pins on the stepper port). BTW KCam now supports defining
parallel pinouts to Step or Direction signals which makes it a lot easier
to configure (it used to be register bits to S&D signals).
